本研究旨在探讨细胞细胞器在猪生殖和呼吸综合征病毒(PRRSV)复制中的作用。作者揭示了一种新的PRRSV复制机制,即病毒通过PRRSV GP5、IP3R和VDAC1的相互作用操纵线粒体-内质网接触,诱导Ca2+过度流出到线粒体,导致线粒体功能障碍和mROS的产生。增加的mROS激活自 ...
综合这些发现,非突触途径,如肾上腺素能受体 - IP3R 轴,可能通过 Ca 2+ 信号调节 OLC 的发育。 随着 OPCs 分化,其突触输入逐渐减少,但少突胶质细胞仍能对神经元活动做出反应,CaM 活动在 pmOLs 和少突胶质细胞中依然存在,只是频率逐渐降低。这表明神经元与 ...
In this important study, Li and others identified cell membrane receptors for juvenile hormone (JH), a terpenoid hormone in insects that regulates their development and reproduction. While ...
Breast cancer is the most common malignant neoplasm in women. Despite progress to date, 700,000 women worldwide died of this disease in 2020. Apparently, the prognostic markers currently used in the ...

其中,主动释放通常由外部刺激触发,比如在激活的 T 细胞中,T 细胞受体(TCR)信号会引发 IP3R 通道介导的 ER Ca 2+ 快速释放。然而,ER 在稳态下被动释放 Ca 2+ 的具体通道,长期以来一直是细胞生物学领域的未解之谜。 初始 T 细胞的稳态对于免疫系统的正常 ...
